SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 237,679, dated February15, 1881.

Application filed December 20, 1880.

To all whom it may concern:

Be it known that I, DANIEL EDGAR, of Adrian, in the county of Lenaweeand State of Michigan, have invented certain new and useful Improvementsin Spring Bed-Bottoms, of which the followingis a specification.

My invention relates to that class of bedbottoms in which the ordinaryhour-glass or Haring bed-sprin gs are permanently attached to the frame,the upper parts of said springs being connected by coiled springs; andmy 1nvention consists in an improved system of connecting said springs,and also in supporting or bracing the outer springs in a bed-bottom bymeans of spiral springs secured to the bedbottom frame and to thebed-springs, as will hereinafter be fully set forth.

In the accompanying drawings, Figure l is a plan view of a portion of abed-bottom made according to my invention; Fig. 2, a perspective view ofa section of my bed-bottom, showing a corner spring; and Fig. 3 is adiagram showing the upper connections of a complete bed-bottom.

The springsA are shown as formed with an elliptical base, a, and aresecured upon the cross-bars B ofthe bed-bottom frame. rIhe upper coil ofeach of the springs A is connected to the adjacent springs by means ofsmall spiral springs C D in the following manner: Each spring isconnected to the springs immediately in front and rear and'on each sideby the short spirals C, and every alternate spring in the transverserows is, in addition to the connections above mentioned, connected, bythe spirals D, with each spring diagonally oppositethat is, with thecorner (No model.)

springs ofthe square of which said spring is the center. To support eachouter spring, A, against inward strain, I brace it by a spiral,E,secured to the side ofthe bed-bottom frame and to one ofthe coils ofthe spring. The corner springs are provided with a bracingspring on eachside.

By this construction I obtain a bed-bottom of great strength,elasticity, and durability, the advantages of which will readily presentthemselves to those familiar with the subject.

I claim as my invention- 1. The combination, substantially as herein setforth, ot' the bed-bottom frame, the springs A, and the horizontalconnectin g-spirals C and D, each spring A being connected with thesprings immediately in front and rear and on each side thereof by theshort spirals C, and each alternate spring A being also connected by thespirals D with the springs diagonally opposite thereto, as shown anddescribed.

2. The combination of the frame, the outer springs, A, and thebracing-springs E, wherebythe springs are elastically braced againstinward strains, substantially as set forth.

3. The combination, with the frame, the springs A, and the horizontalconnecting-spiralsG and D, of the bracing or supporting spirals E,substantially as set forth.

In testimony whereof I have hereunto subscribed my nameV this (ith dayof December, A. D. ISSU.

DANIEL EDGAR.
